WHEEL-HUB.

vSPL'CIPICATION forming part of Letters PatentNo. 362,506, dated May 10, 1887.

Application filed December 27, 1886. Serial No. 222.747. (No model.) l

vof which the followingis a specification.

Our invention relates to improvements in metallic hubs in which metallic spokes are secured a short distance apart and radiate to- Ward the feny it a slight inclination toward each other; and theobjects of our improvements are, first, to provide a hub constructed entirely of metal; second, to provide an elaspleted wheel.

tic hub; third, to provide a hub that can be applied to the standard axle-boxes now in use. We attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents a diametrical section through the hub and through an axle-box with axle in place. This View is a modication of the complete invention. Fig. 2 represents a plan of the hub with the spokes left out. Fig. 3 represents side elevation of the circular binding-wedge. Fig. 4 represents a perspective view of one of the principal portions of the hub. Fig. 5 represents a diametrical section through the complete invention, also through the axle-box to the axle. Fig. 6 represeuts a section and plan of a tubular metallic spoke to be used in connection with this hub. Fig. 7 represents a side elevation of com- Fig. 8 represents a cross-section of the felly (with spokes extending from it) to be used in connection with this hub.

Similar letters refer to similar parts throughoutthe several views.

Referring to Fig. 2, A and B are two cylindrical metallic castings, each being provided with an equal number of ngers running parallel with their axis and formed at equal distances apart, the spaces between the fingers of each cylinder being also equal and admitting the lingers of each other. The fingers of A are exactly like B, except that the sides of the fingers B at B2 and B3 are made concave, while the sides of the fingers ofV A are made convex. Consequently, when the fingers of A are pushed into the spaces between the fingers of B and the fingers of B are pushed into the ispaces between the fingers of A, they will fit together metal to metal, as shown in Fig. 2.

The 'obj ect .of concaving and convexing the sides is to keep the extreme ends o f the ngers from springing down. This form is preferable,- but others would answer the same purpose.

o The fingers should be of exactly the same length, and the spaces in depth should correspond with the length of the fingers, so that when the two are interlocked they will ybear ends to ends. Holes are then drilled in the centers of the joints so formed to t the contracted circular tenons A on the spokes.

B5 represents clearance-spaces between the fingers, their object being simply to save labor in milling the fingers into size and shape.

The fingers, extending downward and rising again, present when interlocked a circular recess with inclined sides. In this circular recess is fitted the circular wedge-band C. It is made in two halves and fits the angulaisides of the fingers, but is not allowed to bear on their tops. The halves of the ring are bolted together by bolts P, which are countersunk into the metal enough so they will not extend above its surface. This ringwedge bears'on all the fingers of A on the side A and on all the fingers of B on the side B4, while all the fingers have clearance on the side opposite from that on which they bear, A3 and B6. Consequently, the circular wedge, when tightcned, slides down the inclines and forces all the :lingers of A against B and all the fingers of B against A, thereby wcdging and binding them together, and also against the spokes, if they be in place.

The cylinders A and B should be bored to tit the cylindrical shield D. The ends of the spokes I should also rest on it. Theshield D is provided with a flange, D. This extends down over the end of the box F, even with the top of the axle G.

E is a hard-rubber sleeve, which is forced between the shield D and the .box F. The flange D prevents it from expanding out at one end and the axle-nut H at the other. The screw L is to keep the cylinders A and B from coming off from D in case they should work loose and the nut H be withdrawn, such a thing being possible but notprobable, as they should fit tightly. This elastic hub has ICO been designed especially for light rapidrunning wheels, which are constantly subjected toa severe concussion between the axle box and hub, caused by violently striking stones and other obstructions in the roads, such violent concussion causing rapid crystallization of the spokes Where they join the hubs.

Our hub presents a very rm but slightly elastic bed, in which the axle and box lie, and, as the weight comes on the axle and the blow on the tire, the rubber will yield enough to ease the recoihwhich will be disseminated througlr ont the rubber.

Fig. l is amodilication of Fig. 5, the rubber E and shield D heilig left ont. This form is adapted to heavy slow-running wheels, where great strength is needed. This hub has been especially designed to be used in combination With the metallic felly and metallic tubular spokes patented by A. O. Hall of this invention, his Letters Patent bearing date December 7, 1886, No. 353,744, the drawings of that patont being identical with Figs. 6, 7, and 8 in the drawings accompanying this specication.

Having described our invention. what we claim as new, and desire to secure by Letters Patent, is

1. A metallic elastic hub having two cylindrical metallic castings, each having a number of horizontal projecting iingers, each casting formed to t one Within the other and to meet shoulder to shoulder, having holes formed in the centers of the line of contact between the two cylinders adapted to receive tubular metallic spokes, having said lingers formed to present when interlocked an inverted circular recess provided with inclined sides, having adapted to and fitting said circular recess a circular split or divided collar provided with bolts or studs and operating when contracted or tightened to diminish the diameter of said Wedgecollar, and operating by bearing on the opposite sides of the inclincs of said recess to force said cylinders and lingers tightly together and embrace tightly the spokesradiating from said holes, having the internal diameter of said cylinders formed to match the external diameter of a metallic shield provided Withailange extending from one end and covering the end of the axle-box, having the space between the shield and the axle-box lled tightly with an elastic substance, all arranged substantially as herein set forth and described.

2. A metallichnbhavingthe cylindrical metallic castings A and linterlockingr and bound together by the circular wedge O, the shield D, rubber sleeve E, and screw L, in combination with the metallic tubular spokes K, having contracted circular tenons A near each end7 the metallic felly F, U-shaped in cross-section, having inwardlyprojecting lugs or ribs placed at equal distances apart upon its circumference, said lugs having grooves fitting tenons of the spokes and made to securely clampthcse tenons by means of rivets passing through the sides of the feliy upon each side of the spokes, all arranged as herein set forth.
